I have been designing a level for a single-player mod, and I was wondering where the best place to learn how to import bots/monsters/opponents for the single player to battle might be.

Can pre-made bots/monsters with AI be downloaded from somehere?

I'm hoping to edit the bot's AI with UnrealScript.

The bots/monsters get more and more advanced, smarter, and more lethal, as the player approaches the mountain.

I'd also liked to have winged beasts/flying bots.

what's the most straightforward way to do this?
